    春夏兩季長毛兔的配種繁殖注意事項

    發(fā)布日期:2019-03-21 來源:http://www.whxfy.cn 發(fā)布人:admin

    想要把長毛兔的養(yǎng)殖做好,我們要把長毛兔的繁殖工作做好,針對更近的季節(jié),我們來講一下春夏兩季長毛兔的配種繁殖的注意事項。
    If we want to do a good job in raising long-haired rabbits, we should do a good job in breeding long-haired rabbits. In view of the recent season, let's talk about the matters needing attention in breeding and breeding of long-haired rabbits in spring and summer.
    長毛兔繁衍無明顯的時節(jié)性,一年四季均可配種繁衍,但因不同時節(jié)的溫度、光照、營養(yǎng)情況不同,對母兔的繁衍性能有一定影響,因而,春季是母兔繁衍的時節(jié)。
    Long-haired rabbits have no obvious seasonality in reproduction. They can breed and multiply all the year round. However, due to the different temperature, light and nutrition conditions in different seasons, the reproductive performance of female rabbits is affected to some extent. Therefore, spring is the golden season for female rabbits to multiply.
    (1)春季。氣候溫和,飼料豐厚,公兔性欲旺盛,母兔配種受胎率高,產(chǎn)仔數(shù)多,是長毛兔配種繁衍的*時節(jié)。3~5月份母兔發(fā)情率高達80%~85%,情期配種受胎率為85%~90%,均勻每窩產(chǎn)仔數(shù)達7~8只,所以,普通兔場應力爭春季能配上2胎。
    (1) spring. With mild climate, abundant feed, strong sexual desire of male rabbits, high fertility rate of female rabbits and large number of offspring, it is the * season of breeding and reproduction of long-haired rabbits. From March to May, the estrus rate of female rabbits was as high as 80%-85%, the conception rate of mating during estrus was 85%-90%, and the number of litters per litter was 7-8. Therefore, the normal rabbit farm should be able to match two births in spring.

    (2)夏季。氣候酷熱,特別是南方各省,高溫多濕,兔食欲減退,體質(zhì)衰弱,公兔常有夏季不育現(xiàn)象,故配種受胎率低,產(chǎn)仔數(shù)少。6~8月份母兔發(fā)情率為20%~40%,受胎率為10%~30%,每窩產(chǎn)仔數(shù)僅2~5只。即便產(chǎn)仔,因哺乳母兔天熱減食,泌乳量少,仔兔衰弱多病,成活率很低。但如母兔體質(zhì)強健,又有遮蔭防暑條件,仍可恰當布置配種繁衍。
    (2) summer. The climate is extremely hot, especially in the southern provinces, where the temperature is high and humid, the appetite of the rabbits decreases, the constitution weakens, and the male rabbits are often sterile in summer. Therefore, the fertility rate of breeding is low and the number of litters is small. From June to August, the estrus rate of female rabbits was 20%-40%, the conception rate was 10%-30%, and the litter size was only 2-5 per litter. Even in the case of puerpera, the survival rate of lactating female rabbits is very low due to fever, fewer lactation, weakness and illness of the puerpera. But if the female rabbit is strong and has the condition of shade and heat protection, it can still arrange breeding properly.
